Remark: To send more bytes in one data stream the NSS signal must be LOW during the
send process. To send more than one data stream the NSS signal must be HIGH between
each data stream.
8.4.3 RS232 interface
8.4.3.1
Selection of the transfer speeds
The internal UART interface is compatible to a RS232 serial interface.
Table 20 “Selectable transfer speeds” describes examples for different transfer speeds
and relevant register settings. The resulting transfer speed error is less than 1.5 % for all
described transfer speeds. The default transfer speed is 115.2 kbit/s.
To change the transfer speed, the host controller has to write a value for the new transfer
speed to the register SerialSpeedReg. The bits BR_T0 and BR_T1 define factors to set
the transfer speed in the SerialSpeedReg.
Table 19 “Settings of BR_T0 and BR_T1” describes the settings of BR_T0 and BR_T1.
